在vagrant box中安裝了基本的centos7的box，但是，該環境沒有安裝編譯軟件，所以要求自行安裝。

1、查看群組安裝的源包數量： yum group list ，搜索Development關鍵字： yum gropu list | grep Development ，得到：

[vagrant@localhost ~]$ yum group list | grep Development
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
   Development and Creative Workstation
   Desktop Platform Development
   Development Tools
   Server Platform Development
 

2、安裝Development Tools包： sudo yum groupinstall "Development Tools"
